Print the Legend
3D printing is a revolution in a whole new dimension.
Poised to become the most transformative technology since the personal computer, 3D printing is inspiring a generation of inventors, engineers, and entrepreneurs to gamble fortunes in a quest to revolutionize the world. This award-winning documentary tracks startups MakerBot and Formlabs as they compete to bring a radically disruptive product to market first, without "selling out" and losing their anarchic, open-source, hacker spirit.
